What will be the value of x in Fe ^ x+ , if the magnetic moment, = 24 BM ?
Options
- A+3
- B0
- C+1
- D+2
Correct answer
D. +2
Step-by-step solution
Given that, magnetic moment, = 24 and = n(n+2) where, n= unpaired electrons gathered 24 = n(n+2) 24=n(n+2)=n^2+2 n n^2+2 n-24=0 n^2+6 n-4 n-24=0 n(n+6)-4(n+6)=0 (n-4)(n+6)=0 n=4,-6 gathered Number of unpaired electrons =4 If oxidation of F is +2 then it has 4 unpaired electrons.
